GLAZlNG-BAR.

SPECIFICATION forming part of Letters Patent No. 275,261, dated April 3, 1883.

Application filed June 15. 1882.

To all whom it may concern:

Be it known that I, CHARLES l'li'LL PENNY- COOK, a subject of the Queen of Great Britain, and residing at Glasgow, in the county of Lanark, Scotland, have invented an Improvement in Glazing-Bars, (for which 1 obtained British Letters Patent dated May 14, 1879, No. 1,930, andstill in force,) of which the following is a specification.

My invention has for its objects to form an improved glazing-bar, or a bar for supporting or retaining plates or sheets of glass for rooflights or other structures for admitting light, by bending or shaping and combining strips of sheet-zinc or other suitable metal also, to replace the putty ordinarily employed for fixing glass by thin sheet-lead applied in a pcculiar and advantageous manner; and, also, to combine the sheet-lead used as a substitute for putty with the glazing-bar, so that the lead may be held in a simple and secure manner, and the entire combination of glass, lead, and bar be thereby rendered less liahle'to derangementl Figures 1 and 2 of the accompanying drawlugs are end elevations of two strips of zinc which are combined together to form the improved glazing-bar. Fig. 3 is an end elevation, showing the parts of the glazing-bar as combined with each other and with lead strips, the lead strips being shown as they are before the glass has been placed. in position. Fig. 4 is a sectional end elevation representing the complete glazing-bar, with portions of two pieces or sheets of glass in position, and having the lead folded and closed down upon them.

The improved glazing-bars are designed more especially to be used for roof-lights, and to be placed parallel to rafters, their upper and lower ends being fixed to horizontal longitudinal frames or purlins. They may, however, be used in other situations or positions, and they may be supported by intermediate purlins when their length renders it necessary. The lower part, A, of the glazing-bar is made out of a parallel-sided strip of sheet-zinc of any suitable length by bending or shaping the same by rolling or drawing operations, or partly by rolling and partly by drawing operations, so as to have a cross-section or end elevation such as is shown in Fig. 1. The essential parts of this piece A are the turnedthe glazing-bar is made out of a strip of sheetzinc similar to that used for the part A, and in a similar manner, but so that its cross-sec tion or end elevation is of the anchor-like form shown in Fig. 2. The metal of the part A is folded together so as to form a double vertical middle part or main vertical web, 8, which may vary in vertical breadth. in diiferent cases, and the edges are turned outward and upward from the bottom of the web 8 to form the wings 9, these wings being shaped to fit inside of the curved parts 6 of the bottom piece, A.

in the drawings the glazing-bar is shown as made for receiving the edges of two adjacent pieces of glass, 10, one one each side of it; and a lead strip, 11, is provided for each piece of glass. The lead strips 11 are shown by thick black lines in Figs. 3 and 4. Each lead strip 11 is placed upon the inside of the wing 9 of the anchor or upper bar-piece, B, and so that part of its breadth at first lies against the side ot' the vertical web 8. The upper piece, B, with its lead strips, is combined with the lower piece, A, by making them slide one upon the other endwise, so that the wings 9, each with one edge of a lead strip, becomes inclosed between the curved part 6 and the infolded part 5; and after the parts are put together the bar may be passed through rollers to compress the parts 5 6 upon the parts 9 and the lower edges of the lead strips. The pieces of glass 10 are placed so as to rest upon the topsof the parts 5 6, and then the upper edges of the lead strips 11 are folded down as closely and tightly as possible upon the glass pieces, which completes the glazing operation. The lead strips 11 not only hold down the glass, but also pre vent the passage of moisture from the outside to the inside. A kind of gutter, 12, is formed under the edge of each piece of glass, and as the glass is not in practice perfectly in contact with the top edges of the parts .5 6 throughout their entire length, moisture due to condensation on the under side of the glass finds its way into the gutters 12 and passes along them to other gutters, or to pipes or receptacles provided at their lower ends.

Instead of making the parts A B of the glazing-bar ofsheet-zinc, they may be made of thin sheet-iron, steel copper, or brass.

What 1 claim as my invention is- 1. The combination of sheets of glass with a glazing-bar consisting; of two pieces, one with curved parts 6 and turned-over edges 5, on which the said sheets of glass rest, and the other piece in the form of an anchor, with wings 9 fitted into said parts 5 6, all substantially as described.

2. The combination of the portion A of a glazing-bar, having curved parts 6 and turnedover edges 5, with the portion B in theform of an anchor, having wings 9 and strips 11, one edge of each strip being inclosed with one 15 of the said wings by a part, 6, and edge 5, and the other edge of the strip being bent down over the sheet of glass, substantially as set forth.

In testimony whereoflhave signed my name 20 to this specification in the presence of two subscribing witnesses. CHARLES HILL PENNYCOOK. Witnesses:

EDMUND HUNT, DAVID FERGUSON.
